The local Witnesses are making arrangements to do that here too. I think it's in poor taste. It takes away all the dignity they have left. But, I guess it's easy time. All you got to do is set up a table with literature and hope someone comes to you.
The local Wal-Mart here pretty much lets anybody set up outside, but they have to be so far away from the entrance. I personally don't like groups asking for money, if I had any extra money to give I wouldn't be shopping at Wal-Mart. But, I do give to charities, but they are ones I know and trust. I don't know if everyone outside the store is on the up and up.
But, the Witnesses plan on just sitting there and hope people come to them and ask questions.
